How to say "mill" in Japanese

• 工場こうじょうJLPT N4approx.Common
  nounCovers mill as an industrial plant — a factory that makes steel, paper, or textiles. The common, general word for a factory, and the usual choice when mill means the facility, not a grinding machine.
  その工場こうじょうは玩具がんぐを製造せいぞうしている。↗

  The factory manufactures toys.
• ミル
  nounCovers mill as the grinding device itself — a grinder, such as one that grinds pepper or coffee beans. A katakana loanword and less common; it names the machine, not a factory.
  飲のむ分ぶんだけ豆まめをローストして、ミルで挽ひくんです。↗

  We roast just enough beans for the amount we're going to drink, and grind them in the coffee mill.
• 摩砕機まさつき
  nounCovers mill as a machine rather than a place: a grinding mill, machinery that grinds or crushes material. A technical word, less common, used for grinding machinery in industrial settings.
• 製材工場せいざいこうじょう
  nounThe word for a sawmill: a plant where logs are sawn into lumber. Use it when mill refers specifically to sawing timber; it does not cover steel mills or grinding machines.
• 製造所せいぞうしょ
  nounA word for a manufacturing plant — factory, works, manufactory. It can render mill in the facility sense, but as a less common word, 工場 is normally the better choice for a mill.

For a mill meaning an industrial plant, 工場 is the default — 製材工場 for a sawmill and 製造所 as a less common alternative — while for the grinding machine itself use 「ミル」 or the technical 摩砕機.
